What is the role of the t-test in calculating the standard error of the mean?

The t-test is often used to compare the means of two groups. The calculation of the standard error of the mean in a t-test relies on the sample standard deviation, the sample size, and the t-statistic. The t-statistic, along with the degrees of freedom, is used to determine the p-value, which indicates the likelihood of observing the results if there is no true difference between the means. The SEM is derived from the t-test results.
